Assembly instructions
using loose components
1. Mains Cold water supply
Open Bag 1.
Take the cold water inlet assembly and fit
in the position shown, not forgetting the
washer on the bottom union. Tighten
loosely to allow for adjustment.
Note: It is important to check that the
safety valve grub screw is tightly fixed,
otherwise the valve can blow off.
Bring the cold mains water to the boiler
in 22mm pipe. Fit a 22mm stop tap.
Assemble the Altechnic UV4 valve and
manifold with Locktite as illustrated.
Connect to the boiler cold inlet utilising
the 22x15mm reducer supplied. Fit the
safety valve by inserting into the hole,
taking care not to damage the O ring
seal. When the safety valve position has
been correctly determined, clamp in
position using the small grub screw with
the Allen key provided. It is IMPERATIVE
that this screw is tightly fixed, otherwise
the valve can blow off.
2. Equal pressure cold water out (Optional extra kit)
Where an equal pressure cold water
supply is required, use the optional equal
pressure cold water kit.
Remove the 22mm compression nut and
cap from the side inlet port of the
manifold. Assemble the pipe with the
compression nut and olive to the
manifold, and the union to the CW valve.
Joints can be loosely tightened until the
whole assembly is ready for final
tightening, and don’t forget the washer
on the lower union.
Where an equal pressure cold water
supply is required, there is a 22mm
connection on the side of the UV4
manifold for this purpose. If this is not
required, use the 22mm cap which is
provided in the UV4 kit to blank off this
port.
3. Gas connection
Open Bag 2 with two pipes.
The 22mm pipe is for the gas, and the
15mm pipe for the towel rail return
connection.
Take the 22mm gas pipe and connect the
gas union valve ½” bsp to the boiler gas
inlet with suitable gas sealant. There is
no valve on the valve plate, so connect
the gas pipe directly to the incoming
22mm gas pipe through the hole
provided.
Fit gas union with loose part of union to
boiler. Connect to 22mm gas supply.
